Robert Brears, Author of Urban Water Security (Wiley) presented a selection of results on best practices in water management from around the world. We share the best practices Robert collected.

Smart water meters are key to intelligent decision-making

With rapid urbanization and climate change increasing water scarcity, cities and their respective water utilities are turning to smart meters and related technologies to manage water more efficiently. Read more here.

NYC’s Big Water Savings Goal

New York City’s demand for drinking water is at its lowest in 50 years even though the city’s population has reached a record high of over 8.6 million people. Not resting on its laurels, the city’s Department of Environmental Protection (DEP) has released the 2018 Water Demand Management Plan to realize further savings. Read more here

Fit for Purpose Recycled Water in Australia

Water recycling makes non-potable wastewater useful, reducing the economic and environmental costs of establishing new water supplies. Read how Australia’s Queensland Urban Utilities provides fit for purpose recycled water to its customers. Read more here.

The Water-Energy Nexus in Athens

Athens Water Supply and Sewerage Company (EYDAP) is the largest water utility in Greece providing services to 4.3 million customers. Read how EYDAP is reducing water-energy nexus pressures here.

How did Cape Town deal with its “Day Zero” water crisis and what can we learn? Intense drought in South Africa’s Western Cape Province has led the world-renowned city of Cape Town to the brink of “Day Zero”. Day Zero was the date at which residents would be forced to collect strictly rationed water supplies from shared distribution taps. Read More

The Texel initiative, known as S/Zout, features food products that emerge from a collaboration between Studio H and Salt Farm Texel, a Netherlands-based enterprise that grows salt-tolerant potatoes, carrots, onions, lettuce, cabbage and barley. Read More

Hut’s research showed that data from temperature-sensing waders worn by the public and shared with scientists, can be used to decide where the most interesting places are to do more detailed and more expensive research.

A flooding costs billions.
Scientists can predict a flooding or droughts using sensors in a river or ditch. With the new sensing pair of waders, fishermen around the world, help scientists.

In previous blogs we mentioned the increasing issues in dry areas in the world. Think of Sao Paulo, Brazil and California, USA, with almost no water anymore in lakes, rivers and aquifers.

All kind of measures have been taken to increase the water use of people and industries. But which technologies are available to increase the water use in agriculture and still can rely on better harvests? Read More

Floodtags offers the local perspective, the ground-truth on floods, by listening to and anticipating on the flood observations of citizens on social media. After filtering and enriching the data with water- and geolocations, Floodtags delivers the ground-truth data as a service for flood management.

The crowd is saving lives during flood disasters. How? FloodTags is receiving all flood related tweets, starting in Indonesia.

Tweets about major floods are being turned into a mapping tool that could be used by emergency services and disaster response teams to evacuate an area, save lives and provide aid. Read More

Companies and public organisations like hospitals, still don’t focus on corporate water risks as largely external to the company.

However, with demand set to increase even further by 55% in 2050 (OECD Outlook 2050) and deteriorating water quality (OECD, Anthony Cox), companies are facing the need to expand their perspectives. Read More

Mega water diversion project China will only solve water shortage of 5%

Enormous water transportation from the South of China to the dryer Northern regions seems to be useless. This is one of the conclusions mentioned in a scientific report which is published in PNAS. China has been building a canal from the South to Peking. A distance of 750 miles (1200 km). Transportation of water will supply only 5% in the water needs of Beijing while the Southern exporting provincies will be running out of water. Read More

Nr. 1 water stressed metropool Tokyo. Picture of the Skyline of Tokyo, with Mount Fuji in the backyard

Want to know which cities suffer from water stress? The Nature Conservancy has published a list of the top 20 of cities with water stress.

Over 500 cities around the world were investigated. In (big) cities like Tokyo, Shanghai and LA, a large number of people in a relatively small area puts a lot of pressure on water supplies, especially during times of drought. Read More

Five million homes in England are at risk of flooding and the government’s own assessment shows climate change is increasing the risk by driving more extreme weather. That’s the conclusion of The National Audit Office (NAO) report published October 5th 2014. “Every £1 spent on flood defences prevented almost £10 in damage”, the report noted. “So ad-hoc emergency spending is less good value than sustained maintenance.” Read More

The Guarani Aquifer, located beneath the surface of Argentina, Brazil, Paraguay, and Uruguay, is one of the world’s largest aquifer systems of the world

The Guarani Aquifer, located beneath the surface of Argentina, Brazil, Paraguay, and Uruguay, is one of the world’s largest aquifer systems. Of course this enormous reservoir is an important source of fresh water for the regio. The countries over the aquifer are also the original four ‘Mercosur countries’. Since 2010 they work together in managing the Guarani Aquifer System.

The Guarani Aquifer is named after the Guarani people, it covers 460,000 square miles.
